Ruffalo has stepped up his opposition to the proposed Paramount–Warner Bros. Discovery merger by targeting Larry Ellison's Oracle connections, arguing the deal would hand excessive combined media and technological power to those involved. His comments come as the merger already faces political and legal scrutiny, and he's framing the Ellison-Oracle link as part of that broader concentration-of-power concern [1].
